vTO .ALL PERSONSn TO WOM THESE PRESENTS MAY COME:

Be it lrnown that I, ALVIN TAPLIN,i-of Somerville, in the county. of.Middlesex, and State of Massachusetts, have invented anew and usefulImprovement in Burners for Lamps; and I `do hereby declare the same tobe fully described in the following specification, and represented inthe accompanying drawings, of which- Figurel is a vertical andtransverse section of a lamp and burner provided with my invention.

`figure 2 is a side elevation of the lamp,- with the burner turned down,for the purpose of enabling the lamp to bef supplied with oil.

In the drawings, A denotes the body,vB the wick-tube, and C the conicaldeector o f the burner, the said deilector being hinged to ihe body, andprovided with a spring-catch, a, to hold it down upon the body. D is thebody or oil-reservoir of the lamp, and b 'is the metallic cap thereof,it being fixed on the neck e of such body,

and having a female screw, d, cut'on its interior periphery in theordinary way.

In the construction of burners as heretofore made, it has been customaryto form the body thereof, at its lower part,.with a male screw, to screwinto .the lamp-cap or mouth'of the oil-reservoir of the lamp.

In carrying out my present invention or improvement, I make the `body ofthe burner' without any male screw, andI hinge to the body aconcaveannulus, E, provided with a lmale screw, e, to fit and screw intothe female screw al of the'lamp-body or cap b. The hinge of the annulusand body is shown atf. A spring-catch, g, may be applied to the body,and so formed asV to catch upon the annulus, and hold-the body downthereto, when necessary `for it to be so held. This attachment totheburner enables the burner t'o be turned down so as to open the mouth'ofthe lamp-cap, for the purpose of allowing oil to berpoured into thesame.u 4

'I am aware thatit isnot new to hinge orso applya lamp-burner to thebody of a lamp as to be capable of being'turned down upon or movedlaterally aside from the mouth of the body. Therefore I donot claim suchin the abstract. I amralso aware of the invention described in theUnited States Patent,rNo. 41,972, granted March 27, 1864, to MarshallBurnett,which consists ofy a. device madeinvtwp pieces,rs o connected astoA enable one to be moved laterally on and olf the other, the lower ofVsuch piecesbeing provided with amale screw, and the upper havingafemalescrew, themale screw being to screw into a lamp-cap, and the femalescrew being'to receive the screw of the bottom ofithe body of a burner..My invention differs materially from the invention of the said Burnett,aswhere he employs two'pieces to accomplish his invention, I employbutone, which is hinged to the burner. i, l V Y V My invention diifers fromthat for which I have recently' applied for a patent, such applicationfor such patent'having been l'ed in the-Patent Oiiice on or about theJfirst day of December, A. 13.11866, such-.invention consistingmainly'in the combination'of,` an annular'cover, provided with a femalescrew "with the lamp-cap, the

twoibeing directly hinged together, so as to'enahle the cover to beturned or moved on and off the mouth of the cap, such cap having nofemale screw cut in it.

It will be observed that the last-mentioned improvementof necessityrequires the cap to be constructed i somewhat larger in diameter than itwould have to be were it to be made in the ordinary way', witha femalescrew of the same size as that of the annular cover hinged to such cap.Thus it will be seen that the invention is inapplicable tocominonlamp-caps, formed with female screws in their mouths. I Y

My present invention enables the burner to be applied toany suchlamp-cap whose screw is of a proper size toA receive and screw upon themale screwof the'ar`1nulnsl hinged to the bottom of the burner, andconse -quent-ly my present improvement n ot only accomplishesV thedesired result, incident to others hreinbefore referred to, but itdoesithis by one annulus only hinged to the burner, and separate fromthe cap of the oilreservoirof the lamp.

My-invention also differs from eitherv of those described in the UnitedStates Patents, No. 39,253, dated July- 14, 186s, No; 46,691, datedMarch 7,1868, ddd No. 56,497', dated July 17, 186e, for in neither ofthem dow .find my improvemenithat is, the annulus made' to screw intothe neck or cap of the reservoir, and-connected with the burner by ahinge only. i V

In Patent No, 39,253, the c'onnectionfwith the annulus is by'screws anda hinge, the screws being formed on the burner and in a separate annulusor lever; thus requiring the burner to have a malescrew. i

Y In Patent No. 46%691, the'burner is formed with aJ sciew, and screwsVdiectly into the neuk or vcap ofthe reservoir, and is held inconnection by a. wire spring' or springs, there being 4no seperate,nnnulus to screw into the neck or cap, ond be hinged to the burner. I.

In Patent No. 56,497 there is no annulus separote from 'and to screwinto the neck or cap of the reservoir, the burnerbeing fixed directly tothe cap, so :Le to turn in a horizontal plane on and od' the same.

Therefore what I claim. asmyl invention, vis-V i l l u My improvedlampburner, constructed with the annulus E, to screw into theneck or capof the oil-reservoir D, and with'theb'ody'A connected with the annulusby a. hinge only; the whole being in order that the body, hy means ofthe hinge and the annulus, inay be 'connected with the resevfv'oit oiits ap, in monner as specified', and the bodybemovable, relatively tos'nehnnnulus, substantilly as andfor the purpose set forth.
